MAGNETO-ELECTRIC MAGHINE.

SPECIFICATION forming part of Letters Patent No. 662,316, dated November 20, 1900.

Application filed July 5, 1900. Serial No. 22,600. (No model.)

To coll whom, it incl/y concern:

Be it known that we, FREDERICK RICHARD SIMMs, a subject of the Queen of Great Britain, residing at 17 Balderton street, Oxford street, in the city of London, England, and ROBERT Boson, a subject of the Emperor of Germany, residing at 22 Oanzleistrasse, Stuttgart, in the German Empire, have invented new and useful Improvements in or Connected with Magneto-Electric Machines,

of which the following is a specification.

This invention relates to improvements in or connected with magneto-electric machines, and chiefly to such machines as are employed 1g in connection with electric-ignition devices for internal combustion-engines. Such machines as heretofore made have usually consisted of an armature arranged between the poles of a magnet and arranged to be oscillated or moved to and fro between the said poles, or instead of oscillating the armature the said armature has been fixed and the current has been generated by the oscillating or to-and-fro movement of an envelop arranged between the armature and the magnet-poles.

Now our invention'has for its object to so construct magneto-electric machines that the envelop inclosing the armature shall be continuously rotated instead of intermittently o oscillated, as has heretofore been the practice. To this end we secure the latter to one end plate and the envelop to another end plate, which is mounted upon the crank-shaft or upon a counter-shaft driven from the said 5 crank-shaft.

To enable the invention to be fully understood we will describe it by reference to the accompanying drawings, in which- Figure 1 is an end view of a magneto-electric machine having a rotary envelop. Fig. 2 is a transverse section of the same. Fig. 3 is a longitudinal section; and Fig. 4. is an end view of the envelop and shaft, drawn to a larger scale. Fig. 5 is a longitudinal section 5 thereof; and Fig. 6 is a transverse section on the line 6, Fig. 5. Fig. 7 is a longitudinal section of a modified construction of magnetoelectric machine with a rotary envelop. Fig. 8 is a plan of the same. Fig. 9 is a transverse section thereof.

Referring to the drawings, a is the baseplate, I) b the magnets, which are secured to the baseplate through the medium of the side plates or disks (Z d, which are screwed to the said base-plate (t and to the pole-pieces cc, which are also provided with pins 0' c, engaging holes in the base-plate a.

c is the armature, (preferably of the Siemens double-T type, as shown,) the said armature beingsecured by screws d to the side plate (1, which also carries the current-collecting terminal 7L. This terminal is insulated from the plate (1 by the bushing h.

t' is the envelop,whieh partially incloses the armature c and is adapted to rotate between the poles c c of the magnet. The said envelop t' is secured at one end to a plate 2', Figs. 3, 4, 5, and 6, by means of tongues 7 i which lit into the groove i formed in the inner face of the said plate and being held thereto by sorewsjj. (Shown in Fig. 4- and in dotted lines in Fig. 5.) The plate "11 is formed with a square hole t', intowhich fits the squared end of the spindle 76, mounted in the bearingl in the end plate d and pro- 75 jecting therefrom. The spindle is adapted to be rotated by any suitable means from the motor-shaft.

Figs. 7, 8, and 9 illustrate a machine similar to that described in Figs. 1, 2, and 3,but wherein the armature is inserted longitudinally into the magnetinstead of transversely, as in the above-described machine. The side-plate d is in this case screwed to the pole-pieces c 0 alone, there being no bar-plates. The terininal h is insulated from the plate d by the vulcanite or other non-conducting bush h, which is incased in 'the bush kg, of brass or the like.

Having now particularly described and go ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is 1. In a magneto-electric machine, the combination with the field-magnets, of a station 5 ary armature and a continuously-rotating segmental envelop interposed between said stationary armature and the magnets, substantially as described.

2. In a magneto-electric machine, the combination with the field-magnets, of the parallel plates, a stationary armature secured to one of said plates, and a continuously-rotating armature supported by the opposite plate and interposed between the armature and the magnets, substantially as described.

3. In a magneto-electric machine, the combination with the field-magnets, of the parallel plates secured thereto, a stationary armature secured to one of said plates, a bearing secured to the other plate, and a continuously-rotatingenvelop having portions interposed between the armature and the magnets and a shaft for said envelop mounted in said bearing, substantially as described.

4. In a magneto-electric machine, the combination with the field-magnets, of a stationary armature disposed longitudinally of said magnets, a continuously rotating envelop provided with a shaft extending in a direction longitudinally of said magnets, said envelop having portions interposed between the armature and the magnets, substantially as described.

5. Inamagnetoelectric machine,the combination with the field-magnets, of a plate disposed transversely thereof and provided with a bearing, a second plate arranged between the magnets parallel to said bearingplate, a stationary armature secured to said second plate, a continuously-rotating envelop interposed between said armature and said magnets, and a shaft for said envelop mounted in said bearing, substantially as described.
